' JAR CLOSURE.

Application filed November 17, 1925. Serial No. 69,599.

My present invention relates in general to containers and has particular reference, to a jar or the like, preferably glass, for packing and dispensing food products such as fruits,

vegetables, meats, fruit butters, spiced products, dairy products, including milk, pickles, coffee, honey and even tobacco or in fact any product which requires an air tight container to preserve the same and with its marketable value enhanced by the appearance and general usefulness of the container. 7

The salient features of the invention will be readily appreciated upon reference to the jar shown in the accompanying drawing which has been selected for the purpose of illustrating the principle of the existing improvements. However, I reserve the right to deviate from the detail construction shown without departing from the spirit of the invention as defined in the subjoined claims.

In said drawing Figure 1 is a view in side elevation and partly in section of a jar showing the application of the invention.

Figure 2 is a top plan view and Figure 3 is a detail perspective view.

Referring now to the drawing in detail 1 represents .a jar or the like which I prefer to produce from molded glass and of a design which will lend a pleasing appearance to the product to be sold therein. The jar should preferably be made with a relatively deep rim 2 around the opening in the same and with a horizontal ledge 3 surrounded by the rim and providing a seat for the cap closure 4. The depth of the rim should be ample to extend at least flush with the top of the closure 4 or even above the same. Since the top of the closure is curved the ledge #3 will be fairly low with respect to the top of the rim.

The rim #2 is notched according to the 11- lustration, as at #5 and #6 with the notches diametrically opposed. In some forms only one notch will be required and in others a plurality of notches will be employed. The notches are made to accommodate the tongues #7 and#8 which extend from the radial flange #9 on the closure. The flange #9 rests upon the ledge #3 and a gasket #10 of rubber or other suitable material is provided to make a tight seal. The inner edge of the gasket is seated in an annular recess #11 in the closure so as to properly place the same and retain it with the closure when the jar is opened.

the respective ends of the same are secured to means adapted for this purpose provided on the inside of the rim. The means shown are recesses #13 and #14 which commence at the notches #5 and #6 and extend part way around the rim. WVith this arrangement the strip may be introduced at the notches #5 and #6 and presented with its ends in the recesses and turned into place. The recesses should be below the crest' of the curved top of the closure so as to realize the desired tension upon the closure.

The length of the recesses #13 and #14. is more or less immaterial in fact relying on the flexibility of the strip they may be quite short and need not start at the notches. Furthermore they may be made on a slant so as to adjust the tension of the strip to a varied degree.

As indicated the jar is preferably made of glass, likewise the cap closure and the only parts of foreign material will be the rubber or the like gasket and the strip which will in most cases be made from bamboo. The sanitary features of the jar are thus assured to a maximum. The appearance also, due to the combination of parts is an important characteristic as the selling possibilities of the product will be enhanced when offered in this jar. Furthermore the jar is capable of being salvaged by the buyer and reused in the home as there is no seal or other parts to be destroyed when opening.

The jar is fully capable of accommodating food products which are to be mechanically or otherwise vacuumized in the jar and in this connection attention is particularly invited to the notches #5 and #6 in the rim #2 which leave portions of the gasket exposed so that an implement may be inserted under the gasket to break the vacuum and thus leave the cap closure readily removable, after of course first removing the strip #12. After the seal has thus been broken the tongues may be used to pick up the closure and remove the same from the jar.

In the case of liquids or semi-liquids the notches #5 and #6 may be used as pouring opening and thus keep the contents out of contact with the rim of the jar, which is a rim'around the opening in the same, opposed open notches on said rim, recesses in the en'- cumference of the rim commencing. at the i open notches and extending around the inside of the rim in opposite directions and terminating in closed ends at diametrically opposed points in the rim; said closure comprising a cap having opposed laterally projecting tongues adapted to occupy the notches in the jar-rim and a resilient strip 7 for holding the elosurewithin the rim of the jar opening, the ends ofisaid strip adapted H to slide inthe recesses in the rim and engage the same through the opposed open slots in the rim." 1

'2. The combination as set forth in claim 1 and in which the jaris provided With a :seat for the closure; the face of said seat being flush with the bottom of the opposed ope-n slots int-he rim, whereby the-limited :aneas of the contact between the closure and seat isexposed. through said slots.

In witness whereof I aifix my s gnature.
